Here is the current forecast discussion on space weather and geophysical activity, issued 2015 Jun 03 1230 UTC.

Solar Activity

24 hr Summary: Solar activity remained at very low levels. Region 2356 (S16W14 Hax/alpha), the largest group on the disk, decayed further in the past 24 hours. A new region of emerging flux in the NE is beginning to show signs of minor spot development and will be monitored for continued growth. All other regions remained stable or in decay through the period.

A filament lifted off the NE limb beginning around 03/0152 UTC and the NW limb around 03/0732 UTC. No available SOHO/LASCO chronograph imagery depicts signatures associated with these events at time of analysis.

Forecast: Solar activity is expected to be very low with a chance for isolated C-flares for the forecast period (03-05 Jun).

Energetic Particle

24 hr Summary: The greater than 2 MeV electron flux was at normal levels and the greater than 10 MeV proton flux remained at background levels this period.

Forecast: The greater than 2 MeV electron flux is expected to be at normal levels for the forecast period (03-05 Jun). The greater than 10 MeV proton flux is expected to remain at background levels throughout the forecast period.

Solar Wind

24 hr Summary: Solar wind parameters continued at nominal levels. Solar wind speeds were around 350 km/s to 380 km/s. Total magnetic field strength remained steady around 5-6 nT through the period. The Bz component was predominantly positive and saw a maximum southward deflection of -4 nT. The phi angle remained oriented in a positive (away) sector.

Forecast: Solar wind parameters are expected to continue at nominal levels for the forecast period (03-05 Jun).

Geospace

24 hr Summary: The geomagnetic field was at quiet levels.

Forecast: The geomagnetic field is expected to remain at mostly quiet levels for the forecast period (03-05 Jun).
